PUNCHlNG-BAG.

Specicaton of Letters Patent.

Patented J' uly 10, 1906.

To all wiz/ont it may concern:

Be it known that I, CHARLES McKENzIE, a citizen of the United States, and a resident of Butte, in the county of Silverbow and State of Montana, have made certainv new and useful Improvements in Punching-Bags, of which the following is a specification.

y invention is an improvement in punching-bavs, such as are used for practice 1n boxing and exercising.

The apparatus embodying the invention includes two bags which are so suspended and adaptedto revolve and swing laterally in vertical planes as to afford special advantages for instruction in boxing and exercise in gen eral.

The details of construction, operation, and combination of parts are as hereinafter described, and illustrated in the accompanying drawings, 'm which# Figure 1 is in part an elevation and in part a section of one form of the a paratus. Fig. 2 is a similar view of a modiiibation. Fig. 3 is an elevation or side view of a modification. Fig. 4 is a vertical section on the line 4 4 of Fig. 3. Fig. 5 is a perspective view of a portion of Vthe apparatus se arated from the parts to which it is normal y attached. Fig. 6 is an enlarged vertical section on the line 6 6 of Fig. 1, and Fig. 7 is a detail view of a hinge connection.

In the illustration shown in Fig. 1 two punching-bags 1 la, which may be inated or solid, are attached to the lower ends of vertical rods or arms 2, which are pivoted at 3 to curved arms 4, having on the inner side horizontal journals 5, by which they are connected rotatively with a support adapted to revolve around a hanger 6. This hanger may have various forms and attachments. In Fig. 1 the hanger is a rod which is bent twice at a right angle, the longer vertical arm being supported in a hollow standard 7, that may be secured to the floor and which may be held from rotation by a clampscrew 8.

In Fig. 3 the punching-bags and the parts `with which they are immediately connected are suspended from a hanger 6a, that has its bearings and su port on a bracket 9, secured to a vertical wa l. In Fig. 2 the attachment is made to a rod 10, that is supported and clamped in a vertical standard 11. The construction and operation of the punching apparatus proper is in all cases the same, the means of support alone differing. A block or hub 12 (see Fig. 1) is secured on the short pendent arm of the hanger 6 by a clampscrew 138L and a tapered nut 13, having its lower end enlarved to form a head which is screwed into sucll block 12, so that in use the two form practically one device which may be readily adjusted higher or lower on the hanger, so as to accommodate the height of the punching-bags to tall or short persons or to conditions of work and exercise.

The arms 14, with which the journals 5 are rotatably connected, are hinged at 15 to extensions 14, which are secured radially in a hub 16, that is adapted to rotate freely on the nut 13, whereby it is also supported by means of the flanged head of the latter. The two parts 14 14n of the horizontal arms are connected by a rule-joint, so that they maintain normally an alined horizontal position, as shown b full lines in Figs. 1, 2, 3. Thus while the ru e-joint 15 allows the outer portion of the arm 14 to rise or be thrown up at an angle, as shown by dotted lines, Fig. 1, a downward movement beyond the horizontal is not permitted. The upward movement only occurs when the bags 1 1EL are struck from below.

To aid gravity 1n returning the bags and their immediate attachments quickly to the normal position, (indicated by full lines,) I apply spiral springs 17 to the articulated arms 14 14, the same extending over the rulejoints 15, as shown in several figures. The journal 5 of the curved arms 4 has an enlarged head 5, and a sleeve 18 is applied to the journal between such head and the adjacent upward bend of the arm 4. The head 5at and sleeve 18 are iitted somewhat loosely in a socket proper in the outer end of the horizontal hinged arm 14, and the sleeve is clamped therein by screws 19. By this means the arms 4, from which the bags are suspended, are held securely and yet adapted to rotate freely in a vertical plane.

It will be seen that by the construction and arrangement of parts thus far described the bags 1 1EL are adapted to rotate in a horizontal plane around the axis provided by the hanger and are also adapted to swing outward and upward in vertical planes on the hinges 15 and that the bags may also oscillate or swing laterally, as indicated by dotted IOO lines, Fig. 4. To provide for aninward movement ofithe bags, as illustrated V7by dotted lines, Fig. 1, I extend the arms 2 upward'be-` yond the pivots 3 .and connect .their upperl ends with a spring-attachment which holds .l

the arms normally vertical or allows their upper ends to swing outward, and thus theibags to swing inward. The said spring attach-A `ment comprises a Hat bar 20, (see Fig. 6,)

1o which Vis adapted to slide in a horizontal bearing formed by two parallel rods 21 v and-al head 22 and whose outward movement is re-n --sistedby a spiralspring 23, the same acting' between the #head 22 and a corresponding ihead22a,which-slides onthe rod21.

.The following statement will serve to-furftherV explain `and lillustrate the` practicalo eri fationand-usefof the apparatus. 'It wil be noted that neither o'f fthe bags 1 la when zo struck lcomes:in-contact lwithany other obgject, -such as an overhead iplatform, as lis.A

Ausual-in the caseof other apparatusof this -lcharacter but, Aon the contrary, each bag when struckswings in-whatever direction the impetusv of the 'blow forces it and immediately vposition it maybeV struckwith the otherhand,

and thus byfblows with'theftwo-hands alter-` mately ithe |revolutionl of athe bags will Ebe continued andthe necessity of i ducking occur at ,each iblow. rlfhus great accuracy `and skill in leading and ducking may-be Iquickly-acfquired. Itfis' also apparent that facility fin' footworkfand side-steppingmaybe easily at-` ftained vby `use lof zthis apparatus, -s'inee @the boxer-maystep out ofthe way of the second bag 1a afterhittingfthe-first, t1, and'thenstep 1in-again andhitthe firstbag 1 with theother hand. "ln otherwords,the boxer may strike bag s1 withthe right hand, vthen'step -back or 5o sidewise-out of the way o'fbag 1a, then stepl lquicklyinagain and strike bag 1 with 'the fle'ftfhand, andsoon. It-will berfurther seen :that upper'cuts may -be 'made or practiced 'with' great ffacility and that 4in vsuchv case the )Lbags .will swing flatera'lly or directly -upward las the case may be. vadapted toswinglr'ight or left `laterally and iupward andalso'to swing upward only. It

Eis apparent that 'since the bags may circle 6o 'around the central lsupport a lboxer `may 'practicein'followingthem the same as gif in-ay siXteen-footring, since he mayadjust-the ap- ;paratus to suit Ihis purpose. "It will 4also ybe seen that anumber ofboxers maypracticefon A6i; =the Irevolving rbags all :.atthesameftime, eachf `-Asfthebag l1r .comes around and approaches the original Thus either bag fis.

lpunching one'or the otherashegets opportunity. The 4hangers -6 and `6a may be clamped so as to be movable; but the bags and theirimmediate supports or attachments are in each case leftfreeftofrevolve on the nut 13. Whether the hanger is fixed or stationary,fthe two bags will still turn thereon.

lThe clamp-screws 19 are ordinarily so ad- ,justed as to merely hold thepsleeves .1S in place, leaving the journals 5 of the ybag-suspending `arms '4 to revolve freely; but the said suspending-screws may be so adjusted as to clamp directlyupon'the journals'5,and

-thus L'hold the arms llffromrevolving. For

this purpose y the sleeves -1'8 are provided-with opposite openings to =receive thepoints of= the screws 19. Thus inpracticeifthe-set-screws holding the arm of l"bag l fbe'screwedfdown and those connected with-bag Als-be loosened then iffbag labe struckfirstit'wouldfrevolve and :pass -over #the head yof the 'party 4who struck it, while the necessityoffduc'king -toO avoid'the bag 1 -vwouldbeapparent.
